Document Type and Number:
WIPO Patent Application WO/2017/167232
Kind Code:
A1
Abstract:
An air conditioning system. A first evaporator (401) and a second evaporator (402) are connected in parallel. A first electronic expansion valve (501) is serially connected to the first evaporator (401), and a second electronic expansion valve (505) is serially connected to the second evaporator (402), so that the opening degrees of the first electronic expansion valve (501) and the second electronic expansion valve (505) can be separately adjusted, the first electronic expansion valve (501) and the second electronic expansion valve (505) can perform position correction according to valve opening position information of the first electronic expansion valve (501) and the second electronic expansion valve (505) stored by the air conditioning system, and separately adjust target positions to calibrated target positions. The air conditioning system can reduce risks of out-of-synchronization of the electronic expansion valves and optimize performance of a control system. Also disclosed are a control system and a control method for the air conditioning system.
